Someone Please Explain

I'm still lost for words when I read about guys raping 5 to 10 year old girls

Trust me, I understand that guys have urges

Hence, there is porno on the Internet.

Satisfy yourself by doing just that

But it REALLY bothers me when sick bastards go out, hunting for young preys to RAPE

Are you fcking kidding me?!!

They are 5 year old girls, you dumb shit

Low life idiots.

Bastards.

And today I read about 5 to 10 year old girls who are pregnant

Mostly because they were raped

But is that possible?

How is it possible to get pregnant when you haven't gotten your period?

I've studied Biology for almost 5 years now

 And I know that girls usually start menstruating at the age of  11-ish

But for 5 year old girls to get pregnant?

Huh??

That's like going against the law of gravity!

Somebody, please give me an explanation.
